Content of H5P footer does not change when container page language is changed

[tmkarlsen]

Today (Edlib 2), the H5P footer language corresponds with the page's language settings, this does not seem to be the case in Edlib 3

We want the current behavior in Edlib 3 as well: Changing language on NDLA's language selector, changes the footer language of H5Ps

So, the images are from Edlib 2?
When using Edlib 3, what language is the footer displayed in?

[tmkarlsen]

The screenshots illustrate the current and desired behavior from Edlib 2.
Using Edlib 3 only results in English for all language contexts in articles on ndla_staging.

Is the language code is sent from facade, @emmachughes?

In the POST to CA, /h5p/{id}, the launch_presentation_locale is set to en. This could be because the GET request to E3 Hub, /content/{id}/embed does not seem to contain any language info, making it default to English.
